Deja vu? If yes, then you might have heard of how Apple offered an upgrade, or some might call it "rental", program when it announced the iPhone 6s and iPhone 6s Plus last September. Or you might have also heard of Samsung's plans to do likewise. While whispers about that upgrade scheme has died out since, it is being resuscitated now that the Galaxy S7 is just around the corner. Or so it is hoped. Korean media report that Samsung might have its own rental system in place by the time the Galaxy S7 flagship hits stores in March.
